This is a major release without many feature changes compared to 2.8.13. The reason we decided to give it a major bump is the drop of Python2 support. From this version on, Luigi stops supporting Python2 for the obvious reason. 3.0.0 release includes [a series of PRs](https://github.com/spotify/luigi/pulls?q=is%3Apr+label%3A%22Python2+deprecation%22+is%3Aclosed) **deprecating Python2**, plus a few other changes listed below. Special thanks go to drowoseque for doing all the great work!
